[Question] Some questions about Wild battle

Hey, in RSE versions, when you're battling a zigzagoon, you can't flee, but the text is not "Can't escape", like in the essentials, there is another way to edit the text than editing the script? (i dont want this text permanent, just for this battle), and when the player's lifebar is in red color the wild pokemon flees.

how can i do it? (that the wild pokemon flees and to change the text when can't escape).

Thanks!
